Oxidative stress has gained prominence in evolutionary biology and ecology, being considered a ubiquitous selective pressure that shapes individual phenotypes from conception to death. I will present evidence for the importance of oxidative stress from two studies. I will mainly focus on the longitudinal and transgenerational study of a captive population of zebra finches where the levels of an important antioxidant, glutathione, were experimentally manipulated during early life. Besides, I will show preliminary results from a captive Japanese quail population where artificial selection lines for high and low reproductive effort (egg size) were established, and linked to oxidative stress levels.
